    sbin/hammer: Fix error message on pfs open/ioctl failure
    
    - "Not a HAMMER root" doesn't seem to be a good error message
      when getpfs() or ioctl(HAMMERIOC_GET_PSEUDOFS) has failed.
    
    - getpfs() returning negative indicates open(2) has failed.
      ioctl(HAMMERIOC_GET_PSEUDOFS) returning negative (particularly
      when caller has set pfs->pfs_id to -1 before ioctl) usually
      indicates the fd has nothing to do with the existing valid pfs.
      It makes better sense with a message like "Invalid PFS path %s"
      or something.
